Spectroscopy of the ${}^1{S}_0$-to-${}^1{D}_2$ clock transition in ${}^{176}$Lu${}^{+}$

Abstract

High precision spectroscopy of the ${}^1{S}_0$-to-${}^1{D}_2$ clock transition of ${}^{176}$Lu is reported. Measurements are performed with Hertz level precision with the accuracy of the hyperfine-averaged frequency limited by the calibration of an active hydrogen maser to the SI definition of the second via a GPS link. The measurements also provide accurate determination of the ${}^1{D}_2$ hyperfine structure. Hyperfine structure constants associated with the magnetic octupole and electric hexadecapole moments of the nucleus are considered, which includes a derivation of correction terms from third-order perturbation theory.
